Blotter is the first comprehensive written account of the history, art, and design of LSD blotter paper, the iconic drug delivery device that will perhaps forever be linked to underground psychedelic culture and contemporary street art. Created in collaboration with Mark McCloud’s Institute of Illegal Images, the world’s largest archive of blotter art, Davis’s boldly illustrated exhibition treats his outsider subject with the serious, art-historical respect it deserves, while also staying true to the sense of play, irreverence, and adventure inherent in psychedelic exploration.
